1500 Seconds To Minutes
There are 3,600 seconds in an hour. The easiest way to convert seconds to hours is to divide the seconds by 3600. To understand the reason for the conversion, it may help to set up the conversion, where you first convert the seconds to minutes and then the number of minutes to hours.

Since there are 3,600 seconds in an hour, the easiest way to convert seconds to hours is to divide by 3,600. For example, 4,500 seconds divided by 3,600 is 1.25 hours. If you end up with a fraction of an hour and want to convert it to minutes, multiply the fraction by 60. In the previous example, multiplying 0.25 x 60 gives you 15, which means 4,500 seconds equals 1 hour. and 15 minutes. Another way to convert seconds to hours is to first convert seconds to minutes, then convert minutes to hours. Start by dividing your seconds by 60, because there are 60 seconds in a minute. For example, if you have 30 seconds, divide by 60 to get 0.5 minutes or half a minute. Divide 0.5 by 60 again to get 1/120 of an hour, or about 0.008 hours. Some people find it useful to do these calculations using a conversion table, where you write the conversion value from seconds to minutes and then from minutes to hours on one line and the changes on the second line. For example, when converting seconds to minutes, make a table with 2 rows and 2 rows. Label the top line “seconds” and the bottom line “minutes.” Write 60 on the top row of the first row and 1 on the bottom row. Second, enter the number of seconds you want to change in the top row, then enter that number divided by 60 in the second row. Repeat the same process in the new table to convert minutes to hours, using the same 60 minutes / 1 hour conversion. To see sample issues, scroll down! Michael A. Lombardi, a test engineer in the Time and Frequency Division of the National Institute of Standards and Technology in Boulder, Colorado, takes up the issue.
In today’s world, the most commonly used numbers are numbers (eg 10), a system that probably came about because it made it easier for people to count using their fingers. The civilizations that first divided the date into smaller ones, however, used different numbers, notably duodecimal (base 12) and sexagesimal (base 60).
Due to evidence of the Egyptians using sundials, most historians recognize them as the first civilization to divide the day into smaller parts. The first sundials were simply stakes placed in the ground that indicated the time by the length and direction of the resulting shadow. As early as 1500 BC, the Egyptians developed a better solar system. A T-shaped bar placed on the ground, this scale was measured to divide the time between sunrise and sunset into 12 parts. This division reflects Egypt’s use of the duodecimal system – the meaning of the number 12 comes mainly from its being equal to the number of lunar cycles in a year or the number of fingers on each hand (three of each. four fingers, excluding the thumb) , making it possible to count to 12 with the thumb. The next generation of stars will form the first representative of what we now call hours. Although the hours in a day are roughly equal, their length varies throughout the year, with summer hours being longer than winter.

Without enlightenment, people at this time considered daylight and the hour of darkness to be two opposite countries, not part of the same day. Without the help of sundials, dividing the time of darkness between sunset and sunrise is more difficult than dividing sunlight. At the time when sundials were first used, however, Egyptian astronomers also first discovered the 36 stars that divided the celestial circle into equal parts. The dark path can be marked by the appearance of 18 of these stars, three of which are given every two hours of darkness when the stars are hard to see. The period of total darkness is marked by the remaining 12 stars, repeating the 12 divisions of the night (another nod to the duodecimal system). During the New Kingdom (1550–1070 BC), this measure was simplified to use 24 stars, 12 of which marked the passage of night. The clepsydra, or water clock, was also used to record the time at night and was probably the finest clock of the ancient world. Time – an example of which, found at the Temple of Amun in Karnak, dates from 1400 BC. – is a vessel with an inclined interior that allows the reduction of water pressure, filled with scales that mark the division of the night into. 12 places in as many months.
When both light and darkness are divided into 12 parts, the idea of a 24-hour day is in effect. The concept of time periods, however, did not begin until the Hellenistic period, when Greek astronomers began using this method for their calculations. Hipparchus, whose work appeared mainly between 147 and 127 BC, proposed dividing the day into 24 equinox hours, based on the 12 hours of light and 12 hours of darkness found on the day of the equinox. Despite this agreement, workers continued to use different seasonal schedules for centuries. (Long hours only became common after the first mechanical clocks appeared in Europe in the 14th century.)
Hipparchus and other Greek astronomers used astronomical methods that had previously been developed by the Babylonians, who lived in Mesopotamia. The Babylonians made a sexagesimal (ie 60) calendar that they got from the Sumerians, who invented it around 2000 BC. Although it is not known why 60 was chosen, it is particularly convenient for expressing fractions because 60 is the smallest number divisible by the first six numbers, including 10, 12, 15, 20, and 30.
Although not used for general calculations, the sexagesimal system is still used for measuring angles, areas, and time. In fact, the two faces of the clock and the circumference of the earth owe their distribution to the number of 4,000 years of the Babylonians.

The Greek astronomer Eratosthenes (who lived between 276 and 194 BC) used the sexagesimal system to divide the circle into 60 parts to create a center of latitude, with horizontal lines running through well-known places in the world of time. A century later, Hipparchus normalized the lines of latitude, making them equal and obedient to the geometry of the world. He also created a line of long lines that are 360 degrees and run from north to south, pole to pole. In his treatise
(circa AD 150), Claudius Ptolemy explained and expanded Hipparchus’ work by dividing each of the 360 degrees of latitude and longitude into smaller parts. Each level is divided into 60 zones, each of which is divided into 60 smaller zones. first division,
The clock shows hours divided into halves, thirds, quarters, and sometimes even 12 parts, but not from 60. In fact, time is not usually understood as 60-minute time. It was not common for the public to think of minutes until the first clocks showing minutes appeared near the end of the 16th century. Even today, many watches and clocks have a resolution of only one minute and do not display seconds.
Thanks to ancient civilizations that determined and preserved the divisions of time, today’s society still thinks of a day as 24 hours, an hour as 60 minutes, and a minute as 60 seconds this mouse. Advances in the science of time, however, have changed the way units are defined. Several times they were derived by dividing astronomical events into smaller units, the International System of Units (SI) at one time defining the second as part of the solar meridian and then about it for golden years. This changed in 1967,
